I know this is my first post but I have been on here for a while and finally signed up today as I'm needing a bit of advice. Well I stripped my vr6 down and it appears both the upper and lower timing chains have snapped. Dont know whats caused it to happen as the engine was only on 98k but here are some pictures of the valves and a bit of the chain tensioner I found inside. I'm going to replace all the valves but will I need new valve seats or new lifters aswell ? Also what can I use to clean the whole head to get all the oil and carbon deposits off ? Can I just use any degreaser or what ?
